The book states main concepts and features of FM realization in frequency synthesizers (FS) with impulse-phase automatic frequency tuning system (IPAFT). The attention is drawn to methods of frequency-modulated synthesizers (FMS) designing, their account, projecting and practical application in radio communication systems. The ready formulae for engineering accounts of FM synthesizers parameters and synthesizers separate nodes designing examples are given.

The monograph is intended for wide range of scientists and engineers who deal with radio means designing at frequencies discrete set and also for universities teachers and students of radio technical specialties during diploma projecting.
